Résumé: The noncentrosymmetric material Hg(IO3)2 with P21 space group symmetry has been synthesised. This compound is thermally very stable (520 [deg]C) and shows a NLO efficiency visually comparable to that of lithium iodate. The crystal structure has been solved in order to relate this efficiency to the IO3 chomophore packing. Simple calculations, based on the bond additivity model, show that both I---O and Hg---O bonds contribute to SHG tensor.
